Biometrics, also known as biometrics-intrusion detection system or biometric verification systems, are one of the most important technological developments in the field of security and criminal justice administration. Biometrics is a combination of different identification methods used together to generate an exact match between a person and a specific characteristic of a specific individual. Biometrics were first developed for law enforcement agencies and were later adopted by security and immigration agencies.
Biometrics are comprised of fingerprints; irises, facial and hand prints; gait; DNA, fingerprints and voice; among others. The primary use of biometrics is to establish identity. Biometrics may also be used to monitor people while they are at a public place such as in a library or a bank. By using a fingerprint, you can establish the identity of a person who is entering a building or is leaving the building. The authorities insist that biometrics database can be effectively utilized for border security, detect criminals, to track and identify terrorists, and for administrative purposes.
In order to have a successful biometric authentication system, identifying characteristics must match well. In general, all physical characteristics of an individual must match those of an entity that is trying to match his personal characteristics. Thus, fingerprints of a person can provide an exact match to the social security number of a person if the former is matched to the latter. For example, a person who has left an expensive wallet behind may be caught red-handed if it is found empty of money. A person’s physical characteristics may also match that of the entity.
Biometrics can further be used in conjunction with id cards. An id card is a device containing information about an individual. Biometrics are used as factors when issuing an id card. Aside from being used as factor for identification, biometrics may also be used as a means of deterring employees from stealing or creating unauthorized access to restricted areas in a work site.
In the past, biometrics were only used for identification, not for facial recognition. However, new developments in the field of computer science have made it possible for biometrics to be used for facial recognition. Previously, facial recognition involved taking a picture of the face of a person, scanning the image using a special device and applying geometric and optical cues extracted from the photo to create a digital image of the face. This was then run through a computer program that used a set of rules or algorithms to make the facial recognition more accurate. Currently, it is possible to take a digital photograph of a person, scan the image, and use sophisticated software to create a high-resolution facial image of that person.
Another type of biometric is fingerprint identification. In this case, special sensors are installed on finger. A computer using a special software processes the finger images and extracts and reads information embedded in the unique fingerprints of the finger. The extracted data is then sent to a special database that contains database files containing information about each individual in the European Union. If necessary, a further image of the finger can also be taken and compared with the extracted data.
Biometrics are used for many purposes by law enforcement officials and others in the security and justice sector. The European Union biometric identification standards are currently under review, with the aim of improving the quality and reliability of such identification systems throughout the EU. In line with this goal, there is a call for more studies to be done on how best to improve recognition methods, and how to enhance the effectiveness of biometric identification. For example, it is now hoped that in the future, fingerprints will be made more accessible so that crime perpetrators will not be able to use false teeth to fool inspectors.
Another benefit of Biometrics is the fact that they help people to stay anonymous when they do not want to reveal their identity. In many cases, this can mean the difference between life and death. For instance, if you are a target for a burglary, but have a set of fingerprints that can be matched, you can call the police instead of giving up your precious belongings to the thieves. Similarly, if you are having problems with identity theft, but know your fingerprints, you can use them to start the process of getting your identity back and stopping it for good.
